Mine Kafon by Massoud Hassani
Hassani, a product designer from Afganistan, build (by hand) a wind-powered device that trips land mines as it rolls across the ground. It is made using bamboo and biodegradable products.
Many of these mines are active and near populated areas in countries like Afganistan and are hard to remove. The UN says that one mine clearance specialist is killed, and two injured, for every 5,000 mines cleared.
Hassani’s cheap and easy to make method has been achieving great results.
In a world of overcomplicated solutions, we need more people who think “Wait, why don’t we just roll a giant freaking ball over it?”
this guy made a katamari for landmines
talk about necessity being the mother of invention though :(
let’s talk about housecats and how fucking weird they are evolutionarily/anthropologically
like who thought it was a good idea to have tiny malicious predators in our homes anyways????? (not us actually)
are they even domesticated????!!!?? (yes) do they even feel LOVE???????!!? (yes)
LET’S LEARN ABOUT CATS

Like all living things, humans are bioluminescent (meaning we glow) – We glow brightest during the afternoon. - weird, interesting & funny facts
i’ve been staring at this for like 5 minutes. so.. what. i don’t think people glow. but this is telling me that we actually emit visible light.. especially in the afternoon?? am i reading this right or what
"all living things" plants. when do the plants glow
science side of tumblr pls
I’m not from the science side of tumblr, but here’s the answer anyways:
Basically, all living things are bioluminescent because every living thing has chemical reactions occurring in their cells. The energy created from these chemical reactions physically manifests as light, thus… all living things naturally glow.
However, this glow cannot be seen by the human eye. In fact, the only way they’ve ever captured this light is through special cameras. Using these ultra special cameras, they’ve imaged subjects’ bodies over 24 hour periods. It has been found out that humans emit the most of this glow during the afternoon (about 4 PM), it is the weakest in the morning (about 10 AM), and the brightest light is emitted from the cheeks, neck, and forehead.
The light is about a thousand times weaker than what humans can perceive.
Basically, it’s a side effect of metabolic reactions. It’s been suspected that humans are bioluminescent for years, but they weren’t able to confirm it until recently thanks to technology and a man named Masaki Kobayashi from the Tohoku Institute of Technology.
10/10 time to answer
you are now offiicially from the science side of tumblr.
and thank you
Titanium dioxide breaks down smog particles in the air, and students in the US have shown that in one year, one roof coated in it can break down the smog from a car that’s driven 17,000 km(10,500 miles). And every day, 21 tonnes of smog could be eliminated by one million treated roofs.

Solar energy that doesn’t block the view
A team of researchers at Michigan State University has developed a new type of solar concentrator that when placed over a window creates solar energy while allowing people to actually see through the window. It is called a transparent luminescent solar concentrator and can be used on buildings, cell phones and any other device that has a clear surface. And, according to Richard Lunt of MSU’s College of Engineering, the key word is “transparent.”

Salmon have serious swimming skills—some travel thousands of miles to return to their original homes to breed. But even though they can jump as high as 12 feet in the air, they can’t manage to get over massive concrete dams that we have built to block their journeys back to their homes. Now one new idea could give them a boost. The plan involves whisking the fish through a long vacuum tube at speeds up to 22 miles per hour and then shooting them out the other end like a cannon.
fuck we’ve made this planet weird
World’s languages traced back to single African mother tongue: scientists.
New Zealand researchers have traced every human language — from English to Mandarin — back to an ancestral language spoken in Africa 50,000 to 70,000 years ago.
Scientists say they have traced the world’s 6,000 modern languages — from English to Mandarin — back to a single “mother tongue,” an ancestral language spoken in Africa 50,000 to 70,000 years ago.
New research, published in the journal Science, suggests this single ancient language resulted in human civilization — a Diaspora — as well as advances in art and hunting tool technology, and laid the groundwork for all the world’s cultures.
The research, by Quentin Atkinson from the University of Auckland in New Zealand, also found that speech evolved far earlier than previously thought. And the findings implied, though did not prove, that modern language originated only once, an issue of controversy among linguists, according to the New York Times.
Before Atkinson came up with the evidence for a single African origin of language, some scientists had argued that language evolved independently in different parts of the world.
Atkinson found that the first populations migrating from Africa laid the groundwork for all the world’s cultures by taking their single language with them. “It was the catalyst that spurred the human expansion that we all are a product of,” Atkinson said, the Wall Street Journal reported.
Atkinson traced the number distinct sounds, or phonemes — consonants, vowels and tones — in 504 world languages, finding compelling evidence that they can be traced back to a long-forgotten dialect spoken by our Stone Age ancestors, according to the Daily Mail.
Atkinson also hypothesized that languages with the most sounds would be the oldest, while those spoken by smaller breakaway groups would utilize fewer sounds as variation and complexity diminished.
The study found that some of the click-using languages of Africa have more than 100 phonemes, or sounds, whereas Hawaiian, toward the far end of the human migration route out of Africa, has only 13, the Times reported. English has about 45 phonemes.
The phoneme pattern mirrors the pattern of human genetic diversity as humans spread across the globe from sub-Saharan Africa around 70,000 years ago.
This gives me LIFE from people who insist all languages (ALL no matter what) derive from latin bases.
Reblogging this for three reasons:
1) It’s awesome and worth knowing
2) It makes sense when you think about, you know, the whole history of human development (from a NOT white supremacist perspective at least)
3) To add that if anyone ever tries to say that all languages are derived from Latin [insert choked sound of disbelief and anger] you can inform their ignorant (probably racist) asses of this: Latin, as far as languages go, is an INFANT. It’s part of a subset of Indo-European languages and MOTHERFUCKER EVEN ENGLISH ISN’T ONE OF ITS DERIVATIVES. (French, Spanish, Italian, Romanian, and Portuguese are, as well as lots of their related languages and dialects, that’s it.) Latin isn’t even remotely old enough to be a mother language. It’s like saying alpacas were the original dinosaurs or some bullshit.
HUH! You dont FUCKING SAY?
WILL YOU LOOK THE FUCK AT THAT!
Not surprising, but this is cool information!
Is that… is that even healthy?
There are sea organisms and fungi which glow in the dark and there’s fireflies and jellyfish which glow in the dark. It doesn’t do them any harm nor does it do the people around them any harm. I would say its pretty healthy, as well as it would mean more photosynthesis happening in cities which mean cleaner air.
I was just curious about how they were doing it and for some reason I didn’t think to click the link. But thanks! It makes more sense now. I was afraid it was some kind of chemical thing.
nah just genetic modification using existing bioluminescent genes. Genetics is really cool, and so is bioluminescence. I mean they’ve already made pigs glow using jellyfish genes and pigs are waaay more complicated than trees iirc. So they’re actually (i think) less likely to muck it up with trees.
In which case
(I like glowy things)
I’m hoping they do this safely in a way that doesn’t make the trees extra susceptible to diseases. Like I know some scientists were breeding a kind of fish that glows under black light or something like that, and they were breeding them in such a way that they got sick really easily (breeding them through incest). I hope that doesn’t happen. (I just hope the trees are safe and stuff ahhh)
